Claims.

An object of my present invention is to provide a Window structure having a number of improved features, the window being durable and inexpensive from a manufacturing and installa- 5 tion standpoint.

A further object is to provide a window including a sheet metal window frame and wood sashes, whereby trouble experienced because of the shrinkage and swelling of the ordinary wood frames combined with wood sashes is reduced, and yet asubstantially weather-tight window is produced in the v:form of a unit which can be readily made in its entirety and assembled at the factory.

Still a further object is to provide a sheet metal window frame having an outer flange for contact with the outer surface of a wall surrounding a window opening in the Wall, and having an inner flange between which and the inner surface of the wall, retainer elements are interposed, thereby rigidly assembling the window frame re1- ative to the wall.

Still a further object is to provide in combination with a sheet metal unitary window frame, wood sashes which are provided with storm sashes supported on and carried by the wood sashes, whereby the wood sashes vmay be opened when desired without the necessityvof additionally opening the storm sashes.

Still another object is to provide a Window structure particularly adapted for roll screens, the sashes of the window structure being hinged, and means being provided for opening and closing the sashes and retaining them in the desired position, such means being operable inside the roll screen so that the roll screen does not have to be rolled up in order to operate the window.

Still another object is to provide a latching means for the sash which is operable inside the roll screen.

Still another object is to provide hinging means for the window sashes which is operable to permit easycleaning thereof.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts o-f the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated'inthe accompanying drawings, in which:

On the' accompanying' drawings -my `window after frame comprises in general a sill member S, side jamb members J and a head jamb member H. The sill S in cross section has a level portion lll and a sloping portion I2. The head member H has a downwardly opening or upwardly depressed portion l.

All four of the members S, J, J and H are provided with outer ilanges i8 and inner hooked flanges i8. The flanges l@ are preferably reinforced by strips lSa spot welded or otherwise suitably secured to the flanges i6.

As illustrated in Figures 14 and 16, the upper and lower ends of the side jamb members J are provided with flanges 20 and 22. These are adapted to overlap the ends of the members H and S as shown in Figures 15 and 17, and to be spot welded thereto, whereby a unitary frame of stamped sheet metal is provided after the parts are thus assembled together.

The strips 15a are somewhat shorter than the flanges I6 and this is for the purpose of permitting the use of angle members 24 to connect the anges I6 of the four frame members together. The member I-I is also provided with a drip flange 28 to prevent the entrance of water behind the upper flange i6 at the head of the window frame.

The window frame thus far described is adapted for mounting in the window opening in a wall W as illustrated in Figure 3. The Window opening is made of the proper size and fitted with a wood sill 28 having a sill block 38 mounted on top thereof, the outer edge of which is coincident with the outer face of the wall W.

The window frame is inserted into the window opening with the anges I6 against that portion of the wall immediately surrounding the window opening, mastic or other sealing agent 32 shown by black shading being used to provide a watertight joint. The flanges I6 are then secured in position by fastening elements such as screws 3d extending through openings 36 in the flanges and into the wall and the sill block 38.

After the window frame is thus mounted, retainer strips R are utilized to more rigidly retain the frame in position, and especially the inner edge in position relative to the inner surface of the wall W. The retainer strips R are angle shaped in cross section and have iianges 38 and 48. The flanges 38 are adapted to be received in the hooked flanges i8, as shown in Figure 18, and then the flanges 4B are swung in the direction of the arrow a to a position against the inner surface of the wall and secured thereto as by nails 42 (see Figure 3). One retainer strip R may be used for each flange I8 if desirable. The inner surfaces or backs of the flanges I8 serve as a plaster ground, this flange, of course, extending around the four sides of the window frame.

In association with my window frame I provide wood sashes S comprising the usual rails, stiles and glass panes 44 puttied in position. In addition to this ordinary construction, however, I rabbet the rails and stiles as indicated at 46 to receive a storm sash SS.

The storm sash comprises preferably a single pane of glass i8 and a sheet metal frame 50. As shown in Figure 4 a liner of rubber or the like 52 is interposed between the peripheral edge of the pane d8 and the metal frame 50. The storm sash SS has a nger clip 54 at its upper edge for convenience in supporting it while placing it in position relative to the sash S or removing it therefrom.

For retaining the storm sash SS in position, I

provide retainer buttons 5G which are pivoted to the sash S as by screws 58 and may be swung to positions either overlapping or out of alinement with the storm sash frame 5l), as shown by full and dotted lines respectively in Figure 19.

By the combination of a sheet metal frame and a wood sash I obtain all the advantages of a wood sash but eliminate the disadvantage of a wood frame combined therewith, and which disadvantage consists of binding of the parts due to swelling of both the frame and the sash. Metal, of course, does not swell and accordingly would retain the same dimensions whether the atmosphere is wet or dry, and therefore only the swelling of the sash has to be contended with. This materially reduces the trouble experienced by the swelling of wood.

I have also made provisions for the mounting of a roll screen housing RH by providing the recess I4 in the head jamb member H. The screen is illustrated at 60 and the guides for the edgesthereof at 62. A binder bar 64 is secured to the lower edge of the screen 50 and is adapted to be pulled down to a position contacting with an auxiliary sill member S, as shown in Figure 6.' Latches 66 are provided for latching the binder bar in this position.

The roll screen housing RH is retained in position by side jamb liners (i8 extending from the upper surface of the sill I8 to the under surface of the housing RH. The side jamb liners 68 are retained in position as by Screws 'l0 and serve as side stops for the sash S as shown in Figures 4 and 11. A head stop and a sill stop are provided at 'i2 and 14 which may be strips of wood retained in position by machine screws 'i3 and 'l5 as illustrated in Figure 3.

The auxiliary sill S" is also formed of sheet metal and is of angle shape. It has a hooked ilange 'i6 contacting with the sill stop 'M whereby to provide a hollow sill to receive the operating mechanism for the sash, as will hereinafter appear. The auxiliary sill S is retained in position by the machine screws 'l5 and additional screws 11. the inner face of one jamb liner 68 to the inner face of the other. The jamb liners 68 are provided with grooves 18 to receive the screen edge guides 62.

Each sash S is hinged to one of the side jamb members J, as illustrated in Figure 10. The hinge is referred to generally by the reference character H. The hinge H is of special design to permit easy cleaning of the sash. It comprises a rst leaf to which is pivoted a second leaf 82. A third leaf S4 is pivoted to the second leaf 82. The leaves 8U and 84 are connected with the ange I6 of the side jamb member J and the upper or lower rail of the sash S respectively. The leaves 82 and 84 are normally latched together by a sliding latch 86 having an enlarged head 88 normally assuming a position in front of the end of the leaf 8d having a slot 98 therein as shown in Figure 8. When the latch 86 is slid toward the right from the position of Figure 8 The auxiliary sill S" extends from a persons arm can be thrust for cleaning the y outer surfaces of the Vsash panes 44. 'In Figure 9 the latched and unlatched positions of the latch 86 are illustrated, and it will be noted that when-latched, the head 88 enters a pocket 94 in the sash so as not tointerfere withthe jamb member J when the sash is swung toclosed position., A deeper recess 96 is provided for-the convenience ofthe operator in engaging the head 88 with his finger whenunlatching the latch; Incidentally if the latch is left in the dotted position whenthe sash is closed, it will engage the jamb and be thereby moved to itsv latched position.

For opening thesash S without the necessity of raising the screen I provide an 'operator comprising a crank 98 journalled in a hub |00 of the auxiliary sill S, and an actuating lever |02. 'Ihe lever |02 is pivoted at |04 and is provided with worm gear teeth |06. The crank is connected to a worm gear 08 meshing with the teeth |06. The arm |62 is` mounted in the hollovtr spacev between the sills S and S", as shown in Figure 6, and has on its outer end a roller i0.

The roller ||0 is adapted to travel longitudinally in a formed channel guide ||2 attached to the lower rail of the sash S'. As shown in Figure 10, when the lever |02 is swung from the dotted position to the full line position, the roller I0 will travel in the direction of the varrow b along the channel track ||2 to the full line position where the window is opened. 'Ihe hooked flange '|6 of the auxiliary sill S" is cut away to accommodate the sweep of the arm |02, the terminal ends of this flange being illustrated at ||4'in Figure 10.

Inforder to hold the sash ina tightly closed position, it is necessary to provide a sash latch in addition to the sash operator just described. The details of this latch are illustrated in Figures 4 and 5. I'he sash has a hook |6 secured thereto with which a cam flange ||8 of a latch lever |20 is coactable. In Figure 4 the parts are shown in engaged but not tightened position. Counterclockwise movement of the cam in Figure 5 will pull the hook H6, and in turn pull the sash Si tightly against the jamb stop 68.

The handle |20 has a stub shaft |22 with which a sector portion |24 of the cam ||8 is connected. The stub shaft |22 extends rotatably through a bushing |26 tted in a bore |28 of the sash stop 68. The back of the sash stop is rabbeted as indicated at |29, the rabbet being of suitable shape to accommodate the hook ||6, the cam |8 and the disk |24. Where the mounting ilange of the screen edge guide 62 extends past the hook ||6, it may be notched to avoid interference with the hook.

After the window frame is placed in position and the plastering finished, the window may be trimmed in the usual manner, as for instance by applying an apron |30, stool |32, side casings |34, head casing |36 and finishing mouldings |38 an |40.

Where a transom type window, as illustrated in Figure 3, is provided, an intermediate head jamb H is provided, this being of somewhat different shape than the head jamb H and serving the purpose of both a head jamb for vthe sash S and a sill for the transom sash TS. 'I'he recess for the roll screen housing RH is in the form of a pair of anges I4' extending toward each other.

Where a mullion type window construction is encountered, two of my window frames side-by sideare used as illustrated in Figure 1l.`

Due to the window frame being made of sheet metal, it is possible to use a very narrow trim on the window, which has been the modern trend.

My window structure is also readily adaptable to the use of Weather stripping. I provide a weather y strip W preferably having the cross sectionil'- lustrated'in Figure 20. An attaching iiange |42 is adapted to t in a rabbet |44 of the side jamb liners 68, while another flange |46 of the weather strip Wis provided with acentral bead |48 and an' edge bead |50. The central bead |48 is adapted to Contact with the outer face of the liner or stop 68.when the window is closed, as shown by dotted lines, while the bead |50 is slightly contracted after passingV over, the corner |52 of the stop 68. The weather stripnW similarlycoacts with the. stop strips 72 and 'i4 at the head and sill of the window.

Some changes may be made in the construction and arrangement of the parts of my device Without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modied forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
